  1. Determine the correctness or otherwise Assertion (A) and the Reason (R).
    Assertion (A): In a power plant working on a Rankine cycle, the regenerative feed water heating improves the efficiency of the steam turbine.
    Reason (R): The regenerative feed water heating raises the average temperature of heat addition in the Rankine cycle.
    1. Both (A) and (R) are true and (R) is the correct reason for (A)
    2. Both (A) and (R) are true but (R) is NOT the correct reason for (A)
    3. Both (A) and (R) are false
    4. (A) is false but (R) is true
Correct Option: A

In a regenerative the heat added in low temperature range is reduced which increase heat addition temperature.
